Network technologies and trends

One of my colleagues went for the ICND 1 (640-822) exam and he failed to pass the exams with a small margin. He got few simulation questions, in which he was suppose the find out the IP address for the router interfaces connected in the topology provided. The show running command was disabled, he was suppose to use alternative IOS commands to determine the IP address assigned to the router interface.

In this scenario don’t panic, the best command to determine the IP address assigned to interface s in any router is “show ip interface brief” or Show ip interfaces. Here is the sample output of these commands

Dear Friends, the most comprehensive Cisco learning game is about to launch! good news for the Cisco Certification aspirers, the Cisco Systems came up with a brilliant idea, it’s a game known as Cisco Mind Share game which covers more than 50% of the CCENT/CCNA certification exam. Currently the Cisco Mind Share game is available as demo version. Which features 5 excitng sections of the full subnet of 15 features? Each level is playable at three difficulty levels based upon your experience and knowledge.

Cisco Systems announces the release of Cisco IOS ® Software Release 12.2(50)SE for Cisco Catalyst 3750-E,3560-E,3750,3560 and 2960 Series Switches. This new release from Cisco Systems introduces Energy wise technology and adds several enhancements in the areas of identity-based networking services and ease of use with Auto Smart ports.

There are several new features included in this release, which are as following.

• Identity-based networking: This release continues to enhance Cisco Identity-based Networking Services (IBNS) with several primary innovations to simplify configurations that support heterogeneous endpoint device environments. The release also includes innovations to transparently integrate with existing network and Internet Protocol Telephony (IPT) infrastructure and to provide IT administrators comprehensive policy enforcement options. These enhancements are covered in detail under “Security and Identity Enhancements” section.

• Auto Smartports: This release extends Smartports to allow dynamic switch port provisioning. The switch uses Cisco Discovery Protocol to determine the type of the device connected to the switch and automatically provisions the port based on the predefined macros. The switch integrates with RADIUS for device authentication and applies the macro based on the RADIUS-assigned tag.

• Wired location services: This enhancement enables switch port tracking of hosts or users connected to switches. As part of the location service, the switch integrates with Cisco wireless Mobility Services Engine, which can be used for host/user lookup in determining the switch connectivity for troubleshooting purposes.

• Cisco Catalyst 3750 Series with Cisco StackWise® enhancements for troubleshooting: This release provides new command-line interface (CLI) for StackWise stats and counters to aid in troubleshooting.

• LLDP-MED integration for class of service/diff services code point (CoS/DSCP): Switch will signal CoS/DSCP settings to connected IP telephone using Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED) (so that the IP telephone can use the values for communication)

• IPv6 packaging changes: Cisco has announced the end of life for Advanced IP Services (AIS). Functionality previously available in AIS has been migrated to IP Services or IP Base as documented in Table 1.

Cisco has appointed a select group of Cisco Engineers to develop a state-of-the-art security force. ‘The Realm.” growing beyond the systems in which they were created into a group of powerful defenders. Forming a unified league of security, the defenders battle Botnets, Malware, Spam and Intruders in the Realm, assuring the safety and security of every citizen on the human network.

‘The Realm.”is an online comic that animates the pane flow and adds voice narration. Creatively it’s an engaging experience, not as complete as a full scale animation but more alive that just a flat 2D image.

What do you think what happens? If a new Cisco Catalyst® switch is placed between any two VTP domains, the Cisco Catalyst® switch will join the VTP domain identified by the first VTP update it receives. Just check the below example.

The VTP domain can be changed to another in a Cisco Catalyst® switch by using the CLI prompt, this is the only way you can change.

The state-of-the-art, interactive simulation software enables you to practice your networking skills with 98 structured labs designed to help you learn by doing, which is the most effective method of learning.

The best thing about the CCENT 640-822 Network Simulatoris the organization of labs. The Skill builder consists of three parts; even the Configuration Scenario consists of three parts where as Troubleshooting scenario has one part. These labs are quite handy and useful. The moment you open any lab the corresponding pdf file opens with the lab instructions. You are supposed to answer few questions in the labs, the LAB topology is explained well.

As I posted before about the Cisco Saudi – Expo 2009 which was held at King Fahd Cultural Center, Riyadh ,Saudi Arabia on 9 & 10th February 2009. The conference was opened by Dr Mohammed Al-Suwaiyel, President of King Abdullah College of Science and Technology, and a keynote from Dr Badr Al Badr, managing director of Cisco Saudi Arabia.

The two-day event for customers and partners included sessions on a number of emerging technologies, including unified communications, collaboration, managed services, and Cisco’s Connected Home and Smart Education systems.The two-day event for customers and partners included sessions on a number of emerging technologies, including unified communications, collaboration, managed services, and Cisco’s Connected Home and Smart Education systems.

The technical presentations were simply great I would say they were meeting the Networkers standards.

Switch C is added to the network connecting via a trunk port to Switch B with no VTP domain configured, in this mode when the Switch C receives the first VTP update from the adjacent Switch B , it will become the part of the VTP domain ITKE as identified in the VTP update.
